A bird watcher meanders through the woods, walking 1.92 km due east, 1.48 km due south, and 3.26 km in a direction 60.0° north of west. The time required for this trip is 1.601 h. Determine the magnitudes of the bird watcher's (a) displacement and (b) average velocity. W N 8c E

** 14. While playing ultimate Frisbee, you run north for 10 m, then east for 30 m, and finally 34 m in a direction 37° south of east (as shown). What is your total displacement (magnitude and direction) during this run? В Ā 37⁰ Ć

A tennis ball is hot off a building with a speed of 63.0 m/s and at an angle of 60 to the horizontal. The tennis ball falls to an altitude 50.0m lower than its starting point  (the ground). a. Find the initial velocity in both the vertical and horizontal directions.  b. How long did it take the ball to hit the ground?

A football is kicked from ground level with an initial velocity of 23.6 m/s at angle of 53.0° above the horizontal. How long, in seconds, is the football in the air before it hits the ground? Ignore air resistance. S

Sheena can row a boat at 3.20 mi/h in still water. She needs to cross a river that is 1.20 mi wide with a current flowing at 1.80 mi/h. Not having her calculator ready, she guesses that to go straight across, she should head upstream at an angle of 25.0° from the direction straight across the river. a.)What is her speed with respect to the starting point on the bank? b.)How long does it take her to cross the river?

Hi I need help please

If we wanted the balls final speed to be exactly 27.3m/s, from what height, hens (in meters), would we need to throw it with the same initial velocity?

When the motorcyclist is at A, he increases his speed along the vertical circular path at the rate of v = (0.04s) ft/s² where s is in ft. Take p = 270 ft. ▼ Part A V If he starts at V₁ = 2 ft/s where s = 0 at A, determine the magnitude of his velocity when he reaches B. = Express your answer to three significant figures and include the appropriate units. μÅ Value Units Submit Part B = P 0 O μà 60° Submit Also, what is his initial acceleration?

An object slides along the inside of a vertical circular track and never loses contact with the track. As it slides upward it slows down, and as it slides downward it speeds up. It's not known whether it's moving clockwise or counterclockwise in the view shown. Match points A, B, C, and D with possible acceleration vectors at those points. Only one of the acceleration vectors shown is possible at each point. A с a B
